Essay

Use cutpoint grouping to organize these data into a frequency distribution.
-Kevin asked some of his friends how many hours they had worked during the previous week at their after-school jobs. The results are shown below. $$\begin{array} { l l l l l l l l l l l l } 6 & 6 & 6 & 4 & 6 & 6 & 9 & 8 & 6 & 4 & 8 & 6 \\6 & 8 & 6 & 6 & 8 & 6 & 6 & 8 & 6 & 8 & 8 & 4\end{array}$$ Construct a frequency distribution. Use 4 classes, a class width of 2 hours, and a lower limit of 3 for the first class.
$\begin{array}{l|l}\text { Hours } & \text { Frequency } \\\hline\end{array}$
